I gotta few for you. But you'll have to agree to buy a table of seats at my Mardi Gras gig at the Ramshead in Annapolis...
But seriously now... I do have a few. Assuming you can blow altissimo on other horns and know how to blow to get up there, here we go.
E3 is simple. Just play your top Eb and add the G key (LH 3).
F3 is harder. Generally I finger F2 and overblow it up to F3.
F#3 is easier. Octave, LH 1 2 3, RH 1, Side Bb.
G3. You finger F#3 and add side C.
G#3. Lip the G3 fingering up there.
A3… though dangerous... You go with Octave, LH 2 3, RH 1 2 3.
